BOLTlNG-REEL.

SPECIFICATION forming part of Letters Patent No. 280,692, dated July 3, 1883, Application filedJune4 1883. (No model.)

To (LZZ whom it may concern:

Be it known that I, Janus M. VAN SLYKE, of Ottawa, in the county of Franklin and State of Kansas, have invented a new and useful 5 Improvement in Bolting-Reels, of which the following is a full, clear, and eXact description, reference being had to the annexed drawings, forming part of this-specification.

The object of this invention is to provide a bolting-reel by which a complete and final result may be accomplished for each reduction of the grain by the use of a single boltingreel.

In the modern system of the gradual reduction of the grain it is important, inthe operation of bolting, that the seam-dirt shall be whipped off the granulations, to the end of removing it entirely atthe first bolting, and

that there shall be no blast produced by the rotation of the reel, which would force the fluff or light powdered waste substance through the cloth bolt, and thereby color the flour.

To secure the above-named objects I pro- 2 5 vide a bolting-reel consisting of three partsviz., a central woven-wire prism-shaped device, into which the reduced grain is fed, the office of which is to whip and scour the seamdirt, germ, and flour from the coarser particles; a wire bolt containing the prismatic scourer, and which separates the coarse bran and granulations of the kernels from the flour andfine waste particles; and, lastly, the outer cloth bolt, which separates the flour from the 3 5 fluff and germ. The prismatic scourer, which is made of woven-wire in order that it may offer sufficient frictional resistance to the reduced grain to thoroughly whip off the seamdirt and flour from the coarser particles, is

rigidly secured inside the wire bolt, and these two are to be rotated in the same direction with the outer or cloth bolt, and at aspeed equal to or greater than that of the outer bolt, in order to get the necessary bolting effect without creating a blast of air, which would force the fluff through the outer bolt with the flour. I thus provide a series of bolts concentrically arranged, each adapted to perform a necessary step at a single operation in the process of bolting after each reduction of the grain,

In the drawings, Figure l is a longitudinal section of my improved bolting-reel, and Fig. 2 is a transverse section of the same.

A indicates the flour-bolt, adapted to rotate uponthe shaft B, and O is a cylindrical wire bolt rigidly connected to said shaft withiu the bolt A.

Vithin the cylindrical bolt 0, and rigidly connected thereto, is a triangular prismatic 6o distributer, scourer, and separator, D, formed of coarselywoven wire, through which the reduced grain is fed to the bolt (J. The action of this distributer upon the reduced grain as the latter falls upon the inner surface of its sides is not only to break up aggregations of the same and to distribute the chop equally to the bolts, x but the frictional contact of the mass against the distributer, while the latter is in rapid motion, whips and scours off the 7c seam-dirt, germ, and other foreign substances, and separates the flour from the bran. The en tire mass of reduced grain thus passes through the distributer and falls upon the curved inner surface of the bolt 0, which by its cylin- 7 drical form presents a continuously-actin g surface, which separates the fine from coarser particles, allowing the former, including the seam-dirt, to fall upon and through the bolt A. In the first bolting, the seanrdirt is thus 8 removed with the low grade of flour.

In order to prevent the creation of a draft of air, which would tend to carry off the seamdirt and a part of the flour with it, thus causing loss, I rotate the bolt 0 and distributer in E the same direction with the bolt A, at aspeed equal to or exceeding that of the latter. The required centrifugal seam-dirt and germ sepa rating effect is thus accomplishedwithout any loss of flour, and better and whiter grades of flour can thus be produced in the subsequent reductions and boltings. lVith this construction the action of a single bolt gives a complete and final result for each reduction, and as each operation is continuous and is done i by the same power and by means of the same elevators, spouts, and conveyers, less space is required than for an ordinary bolt, while a much larger bolting capacity is secured.

E indicates the driving-shaft, having pulleys and belts adapted to give the bolt 0 and distributer D,by means of their small pulley,

I a more rapid motion than that given the bolt A by means of the larger pulley (l.

I am aware that under the old methods of grinding and bolting, it was common to an range a wire screen of coarse mesh inside the cloth bolt to protect the cloth byeonfining the large extraneous substances, as pieces of nails, sticks, &c., thatare sometimes found mixed with the meal. Such screen, therefore, was never used as a bolt lor se 'n'lrating the bran and coarser granulations from the liner partieles, and as such screen was purposel y rotated in the opposite direction to that of the cloth bolt, a blast of air "as created which would be decidedly objectionable, for the reasons above stated, in the manutheture ot" a superior class ot'white flour.

I am also aware that a prism-shaped disintegrator made of stretched parallel wires has l l ,l l l l l l l l been used; but 1n nismatic scoureris formed otwoven wire to secure a greater frictional etteet upon the reduced grain in order to rub oil the seam-dirt and germ, and I do not claim such device, except in combination with the series of bolts.

\Vhat I claim is The combination of the outer bolt, A, the cylindrical wire bolt C, arranged within the bolt A, and the coarse wire work distributor, scourer and separator, arranged within the said bolt the said devices being adapted to be rotated in the same direction with each other,'sullstantially as shown and described.
